Dell 9150 Desktop Motherboard Specs

The Dell Dimension 9150 is a desktop mini-tower computer designed to use Intel Pentium 4 processors and run the Microsoft Windows operating system. As with most Intel computers, it has a system board that integrates a number of functions, including input and output and audio. Unlike many other motherboards, it lacks an on-board built-in video processing system.

Chipset and Processor Support

Dell builds the 9150 system board around Intel's 945P chipset. This chipset supports an 800 or 1066MHz system clock, and integrates with Intel Pentium 4 processors that can fit its Socket-T CPU connector. These include a number of chips with either dual processor cores or, at least, support for Intel's Hyper Threading technology that can allow a single chip to process more commands at a given time.

Supported Memory

The 9150 system board's four memory slots are located near the centre of its top edge. They are designed to hold DDR2 memory DIMMs running at 500 or 667 GHz.The computer can access DIMMs as small as 256 MB or as large as 1 GB for a minimum memory capacity of 512 MB and a maximum of 4 GB.


Dell equips the 9150 system board with a number of PCI and PCI Express slots. From top to bottom, the motherboard features a PCI Express x1 connector, a high speed PCI Express x16 connector, a regular PCI slot, a PCI Express x4 connector and two additional traditional PCI slots. With a total of six slots, the system board allows users to customise the computer with a large number of peripherals.

Internal Connections

In addition to the memory and PCI slots, the Dimension 9150s system board has a number of other internal connections. It features four SATA drive connectors, as well as an IDE drive connector and a traditional floppy drive connector. In addition, it also has connectors for front panel USB and IEEE1394 connections, as well as for processor and system fans.


The motherboard's back panel contains a number of different ports. These include a network port capable of Gigabit Ethernet speeds, five USB ports, and a full array of audio ports for the computer's on-board surround sound audio system. In addition to the back panel, thanks to its internal connectors, the motherboard also supports two front facing USB ports, as well as both an auxiliary microphone input and an auxiliary headphone output.
